alt Hacker NewsYou are probably right but without all the context here one might counter that the concept of authenticity should feature predominantly in this kind of document regardless. And using a consistent term is probably the advisable style as well: we probably don't need "constitution" writers with a thesaurus nearby right?
Perhaps so, but there are only 5 uses of 'authentic' which I feel is almost an exact synonym and a similarly common word - I wouldn't think you need a thesaurus for that one. Another relatively semantically close word, 'honest' shows up 43 times also, but there's an entire section headed 'being honest' so that's pretty fair.
